To all whom it mag/concern:

Be it k own-that 1, Jostrn Hamilton ,,'in the county-of Essex and Cornmonwealth of Massachusetts, have invented certain Improvements in Machines for Treating Stock, ofawhichthe following description, in connection with the acoom pfifflyinge drawing, a specification, like reference characters on the drawlng lndicat- 1 like parts inthe several figures.

"This invention-relates to improvements in machines for treating leather 'or-sin'iilar ma- :terial and in particular to mach-mes lntendi-edftb split died outblanks tobe used as heel liits or rands, or

which is adapted to skive blanks in diilere'nt patterns according. to the various vrelations inuwhich the completed articlesare to be employed-later, and which isra'dapted to be chan ed quickly from the manufacture of one form of article to that 'of'another; I

"fln'the particular'embodlment of tlns 1nvolition shown in the drawings, the form -to"be given the blank is-determinedby a nibl'd or die removably mounted on a roll betweenwhich and-a; second pressure-applygin-g roll the blanks are passed on their way to t hestock treating means, Wh-lCl'l may be a fixed knife, and the change in the form "towhich the blank is skived'i s'obtained b theuse of one or the other of a plural ty-oi di'fi'erently shaped molds or dies,"the" particu'lar mold or die to beused depending upon the shape it is desired to give to the blank, i

Preferably a plurality of blankssuch as referred tofabove are supported in a mega-- zine. from which they are fed forward singly to therolls' which present them to the knife. Prefera'bly,- also, the magazine i will beadjustableto accommodate blanks of i different sizes and the feeding ine'ansgyvill be arranged to advance" the blanks,from the magazine toward *thefikniie to afpoiintat whichthe blank may be gripped by the mold .01 die-carrying roller and its cooperating pressure roller. @etween these rollers the blank is molded into the pamper form so held as it is fed forward into contact with the knife. nsiially desirable to pro Specification of Letters Patent.

above referred to, 'sothat it may beiadapted to feedblanksof different sizes to a position such that theforward edge of such blanks mayhbeigripped by the rolls, and the provisionof such. means constitutes an important feature; of theinvention, while another ,featurecons sts lnthe provlslon of novel means for rendering the said feeding means inactive when desired. The feedingmeans. isarranged to feed the blanks so rolls :at a certain position in the rotation of that they are gripped by the the rolls, this being desirable in order toenable the mold or die carried by one of the rolls to present the blanks to theknife in willbe skivedto the form desired.

- such manner that each part of the blanks A further jfea ture ofthe invention con-" sists in the provision of means,

from those above referred to, for determinseparate mg the position in the rotation of the rolls thereafter, it will be engaged by the mold mounted on one of, the rolls, which is preferably held rigidly against yielding away from-the work. The other roll is preferably "mounted' in yielding bearings and yields to accom-mo'date'varying thicknesses of the work. v It willbe found, however, with the above Whichis an ordinary construction that many blanks,-'Sl.1ch as those for a'horse shoe rand, tend tobecome displaced, as by spreading oryieldingyas they are engaged another important feature of this invention consists'in the provision of means such as guides mounted to engage. the sides of the blanks as they are fed "forward from the magazine to the rolls for preventing this displacement. 1 p Other features of the invention consist in the construction of the lower. rollandof a stripper therefor, and these as well as other details of construction in which reside still furtherflfeaturesof the invention, will be more specifically referred to fill the following: description. p

to limit/this upward movement. Upper roll U is journaled ini'blocks l adjustable in ways" in the frame A and held, rigidly against yielding by wedge-shaped blocks .12

which are operated in' unison by hand wheel- 13. Both rolls are driven so that their adjacent surfaces movein the same direction and preferably at the same rate from an actuating shaft 14 having a pulley'16 which i may be belted to any' suitable source of power.

' "Mountedon the shaft 56f lower feed roll B and preferably against tlre face of' gear disk 15 for 'said'shaf t is a cam 18, herein shown as a block pivotallymounted on said shaft andadjustably secured in the desired angular position on said gear disk g by a pin 20, mountedin said disk and engaging a slot 21 in said camblock. This a cam actuates. ashaft 28 through the medium of an' arm 26 adjustably secured to said shaft and pivotally connected at its other end with'connecting rod 24, which is pivotally mounted on shaft 5, having a slot 23 through which said shaft. passes, and a roller 25 moving in contact with cam' 18. Shaft '2'8i-is mounted to rock in suitable bearings and has-adju'stably. secured thereto a lever of substantially the shape shown, whicl1 is connected thy-a, link'31 to feed slide 32.

A spring 34 may be provided for returning feed .slide32 to'itsinitial position after its actuation by rock-shaft 28. This feed slide' 32 is substantially'fiush with the surface of bed plate D and is provided with guides 33 onwhich it slides in ways formed in'said 1 bed plate, It also carries on its front end a feed. plate 35 adjustably held by screw 36. This feed plate is considerably wider than a side elevation of a 'skiving turning.

beyond said slide 32 vupon the surface of bed plate D on which it is reciprocated. Means are provided for rendering the above described feeding'device inactive, comprising a cam 38 adjustably mounted on a shaft 39 and actuated by a handle LO, and co actiug with lever 30 to rock shaft 28 and force the feed slide in to its limit of movement, in which position roller 25 is held out of contact with all parts of cam 18 as said cam is rotated. 7 A- spring 41 isalso provided acting on shaft 39 and tending to turn it to the position in which the feeding movement of slide 32 is permitted to take place.

In lugs extending from the sides of the bed plate D are removably' mounted rods 4A to support the adjustable sliding brackets- 46, which are clamped in position by screws 45, and are provided with guides '48 on which the front pieces of magazine Fare adjustably mounted. These'front pieces 50 preferably comprise each a block a mounted to slide on guide 48, and cast on the lower edge of a side plate I) tofwhich the side plate b 52 for 'the magazine is removably secured by screw 49, a front plate a forming the partially-inclos'ed fiont'of the magazine, and a screw threaded liig d being formed on the base of front plate 0. These lugs 41 are engaged respectively with right and left screw threads formed on the adjusting rod 5% which is mounted in brackets L6 so as to be held against longitudinal movement, and is provided with a headfnj for convenience in On block a are also mounted guides 56, said guides being held so as to be adjustable independently of the magazine front pieces 50, as by means of set screws 57 and extending rearwardly beyond the sides of the magazine to guide the banks as they are fed from the magazine to the rollersand to prevent 'thcblanks from being displaced or spreading as they are gripped between the mold and pressure roller.

At the rear of themag'azine, a yoke 58 is provided, extending upwardly from the base plate of the machine, to which it is removably secured. This yoke supports a gate 60 which in effect serves to close therear of the magazine. see Fig.6, and has its front 'face curved to correspond approxunatelyto the'sliapeof the lifts in the magazine, and its rear face flat to contact with a supporting or bracing plate 62, extending across the base of the yoke 58. Gate 60 is supported from yoke 58 through the medium of a cross bar Si-adjustably supported from the top of said yoke, as by a screw 65 and carryingtwo rods 66 secured thereto and extending into hollow arms 67 extending upward from said block 60. Preferably a spring 68 will be provided between the end of each rod 06 .arid its hollow arm 67, to force the two apart and a short pin 69 projecting, from slide 32, and rests at'its edgeswhich project 7 Preferably rods 66} areextended; shown to, ha t r of y k m /saga;

Upper roller 'C, whichis hereinsho'wn as the die roller, hasa smooth surface to whichthe die 74:5;is removably, secured by any approved means. The shapeof this die varies corresponding with the character of the work to be done by the machine, whether wedge lifts are to be split, orgou'ge lifts or horse shoe rands. llhe means ofsecuring the die to its roller herein shown consists of a block 75 to which the die is permanently attached, and which fits flush in a recess 6 formed in the surface of the roll, being -secured thereimas shown, by screws, while the 7 die itself extends a suitable distance around the periphery of the roll.

Lower or presser roll B has a roughened surface for more surely gripping the blanksv as they are presented to knife [Preferably said roughened surface consists .of a plurality of corrugated ornotchedrings e between which there are smooth rings f of reduced diameter. On'shaft 5 at each end of roll B there are mounted loosely stripper hangers 76, which hang downward bytheir own weight and are connected at their lower ends by a cross rod 78. On sald rod and between the hangers 76 there are mounted a plurality ofstripper, plates 80 which are spaced apart by any, suitable means, as washers 82, of'substantially' the same thickness as corrugated rings 6. These .plates 80 are curved at their upper ends to correspond substantially .to the curvature of smooth rings 7", and when the stripper 1s assembled extend between said corrugated rings a into contact with smoothrings f.

-of the die.

By turning screw 54 by its head 55, the side walls of the magazine may be adjusted to accommodate blanks of different'width, while the front and sidewalls may be ad' justed together relatively to the "gate which forms the rear wall of the magazlne' is actuated from cam 18' once for every rolls 'B and C. lower edge of gate 60 is beveled slightly as indicated, to assist said block to yield revol-ution ofthe rolls Band C to feed the 'ybottom blank forward frornl-the magazine mainder of the feeding will be accomplished by said rollsj From the fact that rolls B and C are driven so that'their peripheries Inove; at the same speed, and that cam 18 which actuates slide 32 is carried around on the gear disk for one of said rolls it will be's'een that the movement of said slide is correlated with the rotation of the rolls so that the extreme feeding position of said slide corresponds to a certain position of said'rolls in their rotation andthis position can be varied by adjusting cam 18 through the medium ofpin 20 and slot 21. By reason of this correlation between the movements of the ,feed slide and rolls the blanks will be fed forwardso as to be gripped by predetermined point on the surface of said rolls relatively to the die or molds and so that on the continued rotation of said rolls the die may act upon each part of said blank in the manner necessary to present said blank to the treating means in the desired position. By the adjustment of cam 18, above referred to, this point on the surface bf the roll relative to the die,

orthe position of the roll in its rotation, at,

blanks will be moved by said feed plate into position to be gripped by the two presenting Preferably the forward against springs 68 should a blank of unusual thicknessvbe fed forward.- Springs 68 are however of sufficient strength to hold said gate from yielding to permit more than a single blank to be fed forward at a time by reason of frictional contact of such blank with the blank that is being .fed forward.

As the blank is fed forward it is engaged on the sides by guides 56 which hold it a against being displaced or yielding sidewise as it'is gripped by the rolls. This feature is important, especially when blanks for horse shoe rands are to be skived, as the pressure of the die tends to force apart the horseshoe rand and Figs. 10 and 11 diifer- 1-0 two legs of such a blank, but it is applicable also to blanks.

In Figs. 8, -9, 10 and 11 there are illus trated a few of. the various kinds of work which a machine designed according to the present invention is adapted to perform. Fig 8 represents a gou'ged lift; Fig. 9 a

ent forms of wedge or beveled lifts. It Willi-be noted that in work such as shown in Figs. and 11, a single died-out blank of leather yields -two similarly shaped lifts,

one from the fleshside and one from the grain side. In the manufacture of the form of lift showninfFig. 10 the blank is first di-ed 'ou't, substantially in the form .of asquare or-rectangle and is then split diagfonally' to-form two similar wedge shaped died out again to formthe completed li-ft.

Injthe manufacture of the form shown in Fig. '11 the blank is first died out to a suitable form and is then split slantingly soles-to form two similar lifts, each havi'n one'edge beveled as represented in sai I figure.
